“…On the other hand, the Te spectrum demonstrates a strong Raman peak at about 118/120 cm −1 wavenumber. It should be noted that the spectra of few monolayer Bi 2 Te 3 show lines at ~ 93 cm −1 and 114 cm −1 , and they may be attributed to the Se and S doping, as previously mentioned [50,52,54,55]. Furthermore, samples with S=0.00 and S=0.06 clearly exhibit a lower shoulder (≈115 cm −1 ) in the A 1 u mode (due to excess of Te as compared to Bi 2 Te 3 ) leading to A 1 u peak broadening.…”

“…This mode was identified as an A 1 u mode (X peak) observed in nano-crystalline and few-quintuple thick Bi 2 Te 3 [53]. It is significant that the A 1 u mode originated as an active phonon mode in the infrared (IR) is forbidden in Raman for centrosymmetric Bi 2 Te 3 [50,54,55], where the existence of Te1 atoms in the center of Bi 2 Te 3 unit cell makes the IR active modes (A 1 u ) to be odd parity. As the polarizability of odd parity modes does not change, they are often inactive modes for Raman, especially in centro-symmetric molecules [53].…”

“…Many scientists have attempted to produce and characterize Bi 2 Te 3 /PANI composites. [26][27][28][29] Li and his colleagues successfully synthesized Bi 2 Te 3 -PANI utilizing the mechanical blending approach; they discovered that the composite's power factor is lower than both individual compartments. 28 The physical synthesis of Bi 2 Te 3 and PANI hybrid, on the other hand, required mixing and solution mixing.…”

“…27 PANI and Bi 2 Te 3 have been explored structurally and electrically by several researchers. 20,29,30 This research's main originality is highlighting the engineering of new materials with remarkable structural, thermal, and magnetic properties. Additionally, the coupling between PANI and Bi 2 Te 3 after being irradiated with gamma rays which increases cross-linking, and evaluating the physical and chemical properties of PANI/ Bi 2 Te 3 compounds for standing on their new applicability for magnetic and thermistor in the future.…”
